Assassins Creed- Decent series, 1 was the best, 2 was meh and BH was the worst.

Bioshock- Best on the list. Not as good as System Shock 2 but still good. Had potential to be better though.

Mass Effect- Ah, I hate this game. I don't even consider it an rpg. No depth in the gameplay, forgettable characters, re-used texture everywhere, generic scifi story,bad voice acting, bad AI,linear missions. ME2 improved many things but failed because they removed many ...

Everybody is missing the point. CS's graphics don't matter. I still prefer 1.6 over Source. The graphics could be fucking DOOM graphics and I wouldn't mind if the gameplay was good. All they need to focus on is the gameplay and animations because that's important for competitive play.

Hmm well let's see GTA: Vice City had one of the best worlds. That was on console. Two Worlds 1 really did the medieval setting well. Deadly Premonition was the most immersive world I've played this gen. Viking nailed the norse mythology setting. I want to say Limbo but that was more setting than world. Still probably many I'm missing. And I'm a PC gamer.

I think TDM would work as kind of a class based game. Just think of it as a multiplayer game with classes that need to rely on eachother. I really think it could work and I usually hate SP games adding MP. I say do it gearbox, do it.
